Only authorized engineers or service personnel can perform installation and maintenance. If you want to install the UPS by yourself, installation must be under the supervision of authorized engineers or service personnel. If you use a forklift or other equipment to move the UPS, please make sure its loading capacity is sufficient enough to lift the UPS Installation Environment The UPS is designed for indoor use only. Do not install or place it in an outdoor area. Make sure that transportation routes (e.g. corridor, door gate, elevator, etc.) and installation area can accommodate and bear the weight of the UPS, the external battery cabinet and handling equipment. Ensure that the installation area is big enough for maintenance and ventilation. Keep the ambient temperature of installation around 30 C and that of humidity within 90%. The highest operating altitude is 2000 meters above sea level. The UPS is intended for indoor installation and should be placed in an environment with clean air and with adequate ventilation to keep the ambient temperature within the specified operating range. The UPS is air-cooled with the aid of internal fans. Cold air enters the UPS through the ventilation grilles at the front of the cabinet. If necessary, install a system of room extractor fans to avoid the room temperature heating up. Air filters are necessary if the UPS is operated in a dusty environment. Note: The UPS is suitable for mounting on concrete or other non-combustible surface only. The UPS is air-cooled with the aid of internal fans. Cold air enters the UPS through the ventilation grilles at the front of the cabinet and hot air is released through the grilles at the back. Do not cover the ventilation openings. Do not allow unauthorized personnel to enter the installation area. Assign specific personnel to keep the UPS key. For safety concerns, we suggest that you shall: 1. Surroundings of the installation area with CO2 or dry powder fire extinguishers. 2. Install the UPS in an area where the walls, floors and ceilings were constructed by fireproof 12

16 materials. It is recommended that you parallel the external battery cabinets to the UPS. The following clearances are suggested: 1. Keep a clearance of 100cm from the top of the UPS for maintenance, wiring and ventilation. 2. Keep a clearance of 100cm from the back of the UPS and the external battery cabinets for ventilation. 3. Keep a clearance of a 150cm from the front of the UPS and the external battery cabinets for maintenance and ventilation Transportation Warning The UPS is fixed on the pallet with four balance supports. When removing them, pay attention to the movement of the casters to avoid accidents. The cabinet can be pushed forward or backward only. Pushing it sideward is not allowed. When pushing the cabinet, take care not to overturn it as the gravity center is high. If you need to move the UPS over a long distance, please use appropriate equipment like a forklift. Do not use the UPS casters to move the UPS over a long distance. After the UPS has been removed from the pallet to ground, we suggest that at least three people move the UPS to the installation area. One person use hands to hold a lateral side of the UPS, one person hold the other lateral side of the UPS with hands, and one person use hands to push the UPS either from the front side or from the back side until it is moved to the installation area and avoid tipping the UPS. The casters are designed to move on level ground. Do not move the UPS on an uneven surface. This might cause damage to the casters or tipping the UPS might damage the parts inside. Ensure that the weight of UPS is within the maximum weight loading of designated surface of any handling equipment. At the bottom of the UPS, there are four casters to help you to move the UPS to a designated area. Before you move the UPS, please turn the two leveling feet counterclockwise to raise them off the ground. This protects the leveling feet from damage when moving the UPS. Please use sufficient manpower (at least six people) and equipment (e.g. forklift) to carefully move the UPS from pallet to ground. Please pay attention to the movement of the casters to avoid accidents. Figure 3-8: Leveling foot and caster 13

43 5. Interface and Communication As shown in figure 5-1, the Static Transfer Switch (STS) Module includes dry contact Port (X1~X2), and communication port (RS232 Port, USB port, SNMP Card Port) on the front panel. Figure 5-1 Dry contact ports and communication ports Dry Contact No. X1 X2 Function Battery Cabinet Temperature Detection Port reserved function Remote EPO input port 5.1 Battery Cabinet Temperature Detection Port The UPS has battery cabinet temperature detection function. UPS can check through the external battery cabinet temperature detection board to receive battery cabinet temperature. Communication between the UPS and Battery temperature detection board was by I2C communication protocol. X1 is the battery cabinet temperature detection port. The port is shown in Figure 5-2 and described in Table 5-1. Figure 5-2: Battery Cabinet Temperature Detection Port Name Position Description SCL X6.1 I²C communication SCL Signal SDA X6.2 I²C communication SDA Signal +3.0V X6.3 3V Power GND X6.4 GND Table 5-1: Description of Battery Cabinet Temperature Detection Port 40

44 5.2 Remote EPO Input Port The UPS has an Emergency Power off (EPO) Function that can be operated by a remote contact provided previously by user. Users can set the logic (N.C or N.O) of this EPO Function through LCD panel. X2 is the remote EPO input port. The port is shown in Figure 5-3 and described in Table 5-2. Figure 5-3: Remote EPO input port Table 5-2: Description of remote EPO port EPO Logic Setting Position Description N.C X2.1 & X2.2 EPO activated when Opened X2.1 & X2.2 N.O X2.1 & X2.2 EPO activated when Shorted X2.1 & X2.2 If EPO Logic setting is in Normal Closed (N.C), EPO is triggered when pins 1 and 2 of X1 are opened. Otherwise, EPO Logic setting is in Normal Opened (N.O). EPO is triggered when pins 1 and 2 of X2 are opened. Note: 1. EPO action shuts down the rectifiers, inverters and static transfer switch. But it does not internally disconnect the input power supply. 2. The default setting of the EPO function logic is in Normal Opened (N.O). 5.3 Other Communication Interface The RS232 port and USB Port can be used in UPS communication and maintenance or monitoring the UPS information by Monitoring Software. This UPS has built-in facility to fit SNMP Card options. 41

45 6. Maintenance This chapter introduces the maintenance of UPS, including the maintenance procedures of the power module. 6.1 Replacement Procedures Of Power Module Notes 1. Only the customer service engineers can repair the power modules. 2. Remove the power modules from top to bottom, so as to prevent cabinet from toppling over due to high center of gravity. 3. To ensure safety, before repairing the power modules, be sure to use a voltmeter to verify that the DC bus capacitor voltage is lower than 60Vdc, and that the voltages between the earth and the components you are going to work on are under dangerous voltage values; that is, they re lower than 60Vdc or 42.4Vac peak value. 4. The power modules should be repaired five minutes later and installed in the cabinet again ten minutes later after they are removed Power Module Replacement Procedures Confirm UPS is in normal mode and bypass function/source is available. 1. Enter menu control Turn To Bypass YES on the operator control and display panel for manually turn off the inverters. Then, the UPS is transferred to bypass mode. 2. Turn ready switch to position on replaceable power module. 3. Two minutes later, remove the fixing screws on both sides of the front panel of the module and pull the module out from the cabinet. Note: The module will be blocked by a metal safe locker on the left side of the module when the module is pulled out halfway from the cabinet. At this point, you must press the metal safe locker before you continue pulling the module out. 4. After repairing the module, confirm that the DIP switch of the module is set correctly and the ready switch is in unready state. 5. Push the module into the cabinet and tighten the screws on both sides. If it s more than one power module to re-install, please wait for 10 seconds before installing another module. 6. Wait for two seconds before turning ready switch of the module to position, it will be added into the system automatically and begin to work a few seconds later. 7. Press manual control system turn on YES on the operator control and display panel for two seconds to manually turn on the inverter mode. 42
